    <b>1. Introduction</b>
</p>
<blockquote>
    <p>
        Identifies the purpose, background, and objectives of the performance testing within this project.
    </p>
</blockquote>
<p>
    <b>2. System Attributes and Variables</b>
</p>
<blockquote>
    <p>
        Identifies the attributes and variables of the system that uniquely identify the workload for the system being
        modeled.
    </p>
</blockquote>
<p>
    <b>4. Actor Definitions</b>
</p>
<blockquote>
    <p>
        Identifies classes of external clients whose use-case scenarios will need to be modeled to simulate / emulate loads
        on the system-under-test. Additionally this section identifies the proportion to which any actor comprises the load
        for a performance test.
    </p>
</blockquote>
<p>
    <b>7. Actor Attributes</b>
</p>
<blockquote>
    <p>
        Identifies the attributes and variables of each actor that uniquely identify the different characteristics of the
        external clients of the system. For each actor, identifies information such as human or non-human, data-feed rate,
        think time, transaction style, transaction complexity and behavior patterns characterizing the variability in user
        interaction with the system.
    </p>
</blockquote>
<p>
    <b>6. Actor Work Profile</b>
</p>
<blockquote>
    <p>
        Identifies the specific use-case scenarios executed by an actor and the percentage of time or proportion of effort
        spent by the actor executing the use-case scenarios to accomplish their total business responsibilities.
    </p>
</blockquote>
<p>
    <b>3. Work Load Profile</b>
</p>
<blockquote>
    <p>
        For a given profile, identifies the number of external clients being simulated / emulated during the test,
        including the number, type and distribution of the transactions. A profile may be defined in terms of "peak load",
        "average load" and so on.
    </p>
</blockquote>
<p align="left">
    <b>5. Measurements and Criteria</b>
</p>
<blockquote>
    <p align="left">
        Identifies the measurement and criteria to be used to evaluate successful achievement of the identified performance
        objectives. Measurements typically include response time limits or throughput capacity.
    </p>
</blockquote>
<p>
    <b>8. Remote Terminal Emulation Requirements</b>
</p>
<blockquote>
    <p>
        Identifies the requirements and constraints necessary to be addressed in creating a Test Environment Configuration
        that is acceptable for implementing and executing the performance testing.
    </p>
